ABSTRACT

A method of analyzing conversational messages may be provided. The method may include receiving a query defining a timespan of messages, retrieving at least one conversational message associated with the defined timespan from a plurality of interleaved messages, retrieving at least one message author associated with the defined timespan from a plurality authors associated with the plurality of interleaved messages, and generating a visualization of conversational threads based on the defined timespan, the at least one conversational message and the at least one message author, the visualization organized into time intervals based on the defined timespan.

BACKGROUND Field

The present disclosure relates to electronic communication systems, and more specifically, to systems and methods of analyzing and visualizing team conversational data in electronic communication systems.

Related Art

Messaging platforms that allow instantaneous communication between collaborating team members (e.g., MICROSOFT® TEAM) are becoming increasingly popular in organizations as means of team communication. In these related art platforms, data may be generated (e.g., conversation logs) that may be important to understanding how team members work together. This data may provide insights for improving the efficiency of team collaboration. For example, a team manager might use such information to understand the health of team and report team activities to higher management. Additionally, a new employee or existing employee returning from an extended leave may examine the data to learn key aspects of past projects and get on board more quickly.

However, the analysis of team conversational data may be non-trivial and problematic for related art systems for at least two main reasons. First, the growing volume data produced by related art systems and the heterogeneous nature of the data (e.g., containing textual, temporal, and team member information) may hinder users from easily grasping meaningful and critical patterns. Second, multiple topics may be discussed simultaneously during team communication on these platforms, and individual conversational threads may often be interleaved, posing challenges for users to digest and understand.

In some related art systems, visualization may assist in exploring conversational data in an intuitive and interactive way. For example, some related art may attempt to help users understand structural and temporal patterns of conversational threads. Other related art may employ analytical techniques to facilitate the investigation of topics and sentiment of conversations in the data. However, these related art techniques may be limited to explicitly threaded conversational data (e.g., data inherently having a pre-existing threaded component such as emails and forum replies). In the related art, little attention has been done that may the challenges in understanding team collaboration and communication with messaging platforms that generate interleaving conversational data (such as instant message or chat platform data).

DETAILED DESCRIPTION

The following detailed description provides further details of the figures and example implementations of the present application. Reference numerals and descriptions of redundant elements between figures are omitted for clarity. Terms used throughout the description are provided as examples and are not intended to be limiting. For example, the use of the term “automatic” may involve fully automatic or semi-automatic implementations involving user or operator control over certain aspects of the implementation, depending on the desired implementation of one of ordinary skill in the art practicing implementations of the present application.

As mentioned above, messaging platforms for instantaneous messaging among collaborating team members (e.g., MICROSOFT® Team) are gaining popularity in organizations. As these systems become more popular, volumes of conversational data are generated daily as part of team communication activities. This data can provide valuable information in understanding team collaboration, thus further increasing efficiency. However, the data volume may be huge, and the conversations often intertwine with each other. To address these problems, example implementations of the present application may provide a visualization system for analyzing team conversational data. In some example implementations, such a system may use calendar based interface that may allow users to explore massive message logs at variable time scales (such as year, month, week, and day). In some example implementations, the system may also integrate analytical methods into a pipeline that disentangles interleaving conversational threads, and summarizes their content from different aspects with a novel visual representation. Example implementations may also provide a novel visual representation of conversational threads, which can illustrate both overall activity trends of threads and detailed information (e.g., keywords and owners of individual posts).

FIG. 1A illustrates a schematic diagram of an overall architecture of the messaging visualization system 100 in accordance with an example implementation of the present application. Further, FIG. 1B illustrates a flow chart of a process 101 for visualizing message or post data in accordance with an example implementation of the present application. As illustrated, the system 100 includes a database 105 storing the conversation data and conversational logs. At 165 of the process 101, a timespan query 110 is received or executed and query results 10 are retrieved that may include user information 115 (at 175 of process 101) and post information 120 (at 170 of process 101) within the queried timespan from the database 105. The timespan query may be specified by a frontend visualization 12 (e.g., a user interface or UI) provided to a user performing analysis or data review. FIGS. 2-8 discussed below all illustrate example implementations of a UI that may be used to specify the time frame for the query.

Based on the retrieved query results (e.g., the retrieved users and retrieved posts), a de-threading operation may be performed at 185 to separate the interleaving conversations into single conversational threads. The de-threading operation at 185 is not particularly limited and may include using one or more neural networks to calculate similarities between pairs of posts or messages in the conversation data based on detected content features in the posts or messages. Based on the calculated similarities, pairs of posts may be linked together to form threads. Other de-treading operations may be apparent to a person of ordinary skill in the art. The de-threading operation at 185 may produce a set of conversational threads 135 as illustrated.

Prior to, subsequent to, or in parallel with 185, keywords may be extracted from each post using a keyword extraction method at 180. For example, natural language analysis may be used to detect the content of textual messages and extract keywords. Similarly, object recognition, facial recognition, or any other visual recognition techniques that might be apparent to a person of ordinary skill in the art may be used to summarize visual data associated with posts or messages and extract keywords from the summarized visual data. Further, voice recognition, audio identification, or any other audio recognition techniques that might be apparent to a person of ordinary skill in the art may be used to summarize audio data and extract keywords from the summarized audio data. The keyword extraction operation at 180 may produce a set of keywords 140 associated with each of the posts 120.

All the original and derived information, including users 115, posts 120, threads 135, and keywords 140 may be provided to the frontend visualization 12 as needed to produce one of a series of views 145-160 at 190 of process 101. For example, the available views may vary depending on a specified time scale (such as a year view 145, a month view 150, a week view 155, and a day view 160). Further, the type of data requested by and provided to the front visualization may vary depending on the view (145-160). For example, the year view 145 may only request and receive user data 115 and post data 120. Similarly, the month view 150, week view 155, and day view 160 may each request and receive user data 115, post data 120, thread data 135 and keyword data 140. In some example implementations, the threads 135 and keywords 140 may be pre-computed and stored in the database to increase the performance initially, or, when requested, computed and stored back to the database to increase performance for future queries.

FIGS. 2-8 illustrate several User Interfaces (UIs) that may be used as front end visualizations in accordance with example implementations of the present application. The analysis of team communication activities provided by example implementations may range from different lengths of time periods due to different user needs. For example, a manager who wants to get an overview may only need to look at monthly (FIG. 3) or yearly data (FIG. 2) at a higher-level to get reflections of how projects have advanced and how team members have interacted with each other. Conversely, a team member may want to examine conversations in the past week (FIGS. 4-8) at a relatively lower-level to summarize activities they have involved. Moreover, the intensity of team activities may often varies a lot across time, which may cause difficulty in identifying critical information from conversational data. Example implementations of the present application may provide a multi-scale method that presents the data in different time scales including yearly (FIG. 2), monthly (FIG. 3), weekly (FIG. 4-8), and daily views (illustrated in FIG. 5 embedded as part of the weekly view), based on a calendar scalable UI.

FIG. 2 illustrates a UI 200 illustrating a yearly view of the front end visualization 12 of an example implementation of the present application. The UI 200 may be displayed on a display device (e.g., a cathode ray display, an LCD display, an LED display, an OLED display, a touch screen display, or any display that might be apparent to a person of ordinary skill in the art) associated with a computing device such as the computing device 1605 illustrated in the computing environment 1600 of FIG. 16. As discussed above, the yearly view UI 200 only requests and received the user data 115 and the post data 120 only and does not request thread data 135 or keyword data 140.

As illustrated, the year view UI 200 may provide an overview (represented by the area within each of the exemplar circles 215 provided) of team conversational activities for each day during the year. In some example implementations, the overview 215 provided includes a pair of triangles 205, 210 representing the number of users posting (triangle 205) and the number of posts (triangle 210) each day. The color hues of triangles 205, 210 for each day may correspond to the numbers of users posting and posts being posted, with darker hues corresponding to larger numbers. In other example implementations, the two triangles may encode for other attributes of the data other than just the numbers of users and posts. For example in some implementations the triangles may encode for message sentiment, and/or numbers of topics. Further, in some example implementations, the user may have an option to choose which attributes they want to see on the calendar.

As may be apparent the yearly view UI 200 may provide a user with an over view of which parts of the year have the largest number of posts (darkest days) and which parts of the year have the lowest number of posts (lightest days). For example, the middle of July shows a lot of active both in terms of users posting (dark orange) and posts being posted (dark purple). Conversely, the last two weeks of December show very low levels of activity both in terms of users posting (light orange/almost white) and posts being posted (light purple/almost white).

FIG. 3 illustrates a UI 300 illustrating a monthly view of the front end visualization 12 of an example implementation of the present application. The UI 300 may be displayed on a display device (e.g., a cathode ray display, an LCD display, an LED display, an OLED display, a touch screen display, or any display that might be apparent to a person of ordinary skill in the art) associated with a computing device such as the computing device 1605 illustrated in the computing environment 1600 of FIG. 16. As discussed above, the monthly view UI 300 requests and receives the user data 115, the post data 120, the thread data 135, and the keyword data 140. The monthly view UI 300 may be navigated to from the yearly view UI 200 of FIG. 2 by clinking or selecting one of the displayed months.

As illustrated, the month view UI 300 may illustrate each separate conversational thread discussed daily as hollow black-line circles 305. For example, the UI 300 of FIG. 3 illustrates that two separate conversational threads (305A, 305B) occurred on July 11, and four separate threads (305E, 305F, 305G, 305H) occurred on July 20. Conversely, only one conversational thread 305C occurred on July 14 and one conversational thread 305D occurred on July 18. This may allow visualization of what projects team members were working on and talking about for a given week.

Within each thread (305A-305H), participating team members may be represented by individual solid circles (310A-310D), where the color indicates person identity and the size indicates their posting activity level in that particular thread. For example, orange circle 310A may correspond to user “Jon Jones” who was a large contributor to thread 305A and thread 305B on July 11, but a smaller contributor to thread 305G on July 20. The UI 300 may also allow visualization of which users contribute to multiple threads (e.g., user Jon Jones 310A, who contributes to many different threads (e.g., all four threads 305E-305H on July 20). Individuals identified as large contributors to individual threads (e.g., many posts to a single thread) might be considered critical team members. Further, regular (e.g., frequent) contributors to multiple threads might be considered “thought leaders” within the organization. The UI 300 may allow critical team members or thought leaders to be identified.

In other example implementations, the color of the solid circles may encode for other attributes of the data other than just the user or author information. For example in some implementations the circles may encode for message sentiment, and/or detected user emotion. Further, in some example implementations, the user may have an option to choose which attributes they want to see on the visualization.

Additionally, in some example implementations, the UI 300 may also provide a social graph visualization (indicated by the area within the circles 315) each day in this month. This social graph visualization 315 may illustrate the social network of team members (310A-310D) based on the threads they are involved. In this social graph visualization, a node represents a team member (310A-310D), and a link 320A, 320B represents that they talk to each other in one thread. This may allow visualization of the team dynamics based on the chat or message posts.

FIG. 4 illustrates a UI 400 illustrating a weekly view of the front end visualization 12 of an example implementation of the present application. The UI 400 may be displayed on a display device (e.g., a cathode ray display, an LCD display, an LED display, an OLED display, a touch screen display, or any display that might be apparent to a person of ordinary skill in the art) associated with a computing device such as the computing device 1605 illustrated in the computing environment 1600 of FIG. 16. As discussed above, the weekly view UI 400 requests and receives the user data 115, the post data 120, the thread data 135, and the keyword data 140. The weekly view UI 400 may be navigated to from the monthly view UI 300 of FIG. 3 by clinking or selecting one of the displayed weeks.

The week view UI 400 illustrates temporal activities of conversational threads within a week using curves 405A-405F. In each curve, 405A-405F, the vertical axis may represent time of each day. As discussed in greater detail below, the lateral movement of each curve on an X-axis along the Y-axis of each curve represents number and sequence of posts occurring throughout the day (e.g., the greater the number of posts the more lateral movement on the X-axis). The number of posts occurring may correspond to the absolute value on the X-axis along the Y-axis. For each curve, participating users (e.g., team members) may be are color-coded similar to the color coding associated with the monthly UI 300 discussed above. For each curve 405A-405F, a gray background 410 may be provided at areas of posting to illustrate the volume of posts across time.

In other example implementations, the color coding may encode for other attributes of the data other than just the user or author information. For example in some implementations the color-coding may encode for message sentiment, and/or detected user emotion. Further, in some example implementations, the user may have an option to choose which attributes they want to see on the visualization.

Additionally, in some example implementations, the UI 400 may also include a box plot region 420 illustrating a comparison for each displayed day to daily averages of days within the remainder of the year. For each day, a box plot 425 may be provided illustrating comparisons between users posting per day and the daily averages of days within the remainder of the year. Additionally, for each day, a box plot 430 may also be provided illustrating comparisons between total posts per day and the daily averages of days within the remainder of the year.

FIG. 5 illustrates a UI 500 illustrating a daily view embedded in a weekly view of the front end visualization 12 of an example implementation of the present application. The UI 500 may be displayed on a display device (e.g., a cathode ray display, an LCD display, an LED display, an OLED display, a touch screen display, or any display that might be apparent to a person of ordinary skill in the art) associated with a computing device such as the computing device 1605 illustrated in the computing environment 1600 of FIG. 16. As discussed above, the daily view UI 500 requests and receives the user data 115, the post data 120, the thread data 135, and the keyword data 140. The daily view UI 500 may be initiated from the weekly view UI 400 of FIG. 4 by clicking or selecting one of the displayed days.

Similarly to FIG. 4 discussed above, the UI 500 illustrates temporal activities of conversational threads within a week using curves 405A-405F. However, the day view UI 500, which is embedded within the week view UI 400, shows more details of the conversational threads represented by the curves 405A-405F within a day. For example curve 405B illustrates a plurality of posts, each post encoded as a small circle 505 color-coded with team members, and the gray background areas 510 also shows temporal post volumes. In addition, key phrases are extracted and shown in regions 515 along the side of the curves 405B-405E. Detailed information of generating this visual representation is discussed in greater detail below.

In other example implementations, the color coding may encode for other attributes of the data other than just the user or author information. For example in some implementations the color-coding may encode for message sentiment, and/or detected user emotion. Further, in some example implementations, the user may have an option to choose which attributes they want to see on the visualization.

Additionally, in some example implementations, the UI 500 may also include a box plot region 420 illustrating a comparison for each displayed day to daily averages of days within the remainder of the year. For each day, a box plot 425 may be provided illustrating comparisons between users posting per day and the daily averages of days within the remainder of the year. Additionally, for each day, a box plot 430 may also be provided illustrating comparisons between total posts per day and the daily averages of days within the remainder of the year.

FIG. 6 illustrates another UI 600 illustrating a daily view embedded in a weekly view of the front end visualization 12 of an example implementation of the present application. FIG. 7 illustrates an enlargement of the daily view region of the UI 600 illustrated by the broken box VII of FIG. 6. FIG. 8 illustrates an enlargement of another region of the UI 600 illustrated by the broken box VIII of FIG. 6. As the UI 600 includes features similar to the UI 500 illustrated in FIG. 5, similar reference numerals may be used in reference to similar aspects.

The UI 600 may be displayed on a display device (e.g., a cathode ray display, an LCD display, an LED display, an OLED display, a touch screen display, or any display that might be apparent to a person of ordinary skill in the art) associated with a computing device such as the computing device 1605 illustrated in the computing environment 1600 of FIG. 16. As discussed above, the daily view UI 600 requests and receives the user data 115, the post data 120, the thread data 135, and the keyword data 140. The daily view UI 600 may be initiated from a weekly view UI similar to the UI 400 of FIG. 4 by clicking or selecting one of the displayed days.

Again, the UI 600 illustrates temporal activities of conversational threads within a week using curves 405A-405F. However, the day view UI 600, which is embedded within a week view UI similar to the UI 400 of FIG. 4, shows details of the conversational threads represented by the curves 405A-405F within a day. Again, curve 405B illustrates a plurality of posts, each post encoded as a small circle 505 (505A-505F illustrate specific circles associated with messages or posts 610A-610F displayed in the pop-up window 605 discussed below) color-coded with team members, and the gray background areas 510 also shows temporal post volumes. In addition, key phrases are extracted and shown in regions 515 along the side of the curves 405B-405E.

In other example implementations, the color coding may encode for other attributes of the data other than just the user or author information. For example in some implementations the color-coding may encode for message sentiment, and/or detected user emotion. Further, in some example implementations, the user may have an option to choose which attributes they want to see on the visualization.

Additionally, in some example implementations, the UI 600 may also include a box plot region 420 illustrating a comparison for each displayed day to daily averages of days within the remainder of the year. For each day, a box plot 425 may be provided illustrating comparisons between users posting per day and the daily averages of days within the remainder of the year. Additionally, for each day, a box plot 430 may also be provided illustrating comparisons between total posts per day and the daily averages of days within the remainder of the year.

In UI 600, pop-up window 605 may be produced by selecting one of the daily curves (e.g., 405D) or one of the circles 505A-505F. In the pop-up window 605, the raw messages 610A-610F represented by each of the circles 505A-505F highlighted on the daily curve 405D. As illustrated each of the raw messages 610A-610F is displayed with the name of the poster/author 615, which is color coded to correspond to the color of the circle 505A-505F. Each of the raw messages 610A-610F is also displayed with the raw text 620 of the post or message 610A-610F.

In other example implementations, the color coding may encode for other attributes of the data other than just the user or author information. For example in some implementations the color-coding may encode for message sentiment, and/or detected user emotion. Further, in some example implementations, the user may have an option to choose which attributes they want to see on the visualization.

The curves 405A-405F illustrated in FIGS. 4-8 above are not limited to the display of daily posts and can be used to visualize other data. FIG. 9 illustrates a UI 900 with a generalized curve 905 showing a plurality of posts or messages 910A-910H distributed over a temporal range (Y-axis). The X-axis of the curve may correspond to a number or quantity of posts occurring within small temporal segment (temporal bin) as discussed in greater detail below. Similar to the daily curves discussed above, the generalized curve 905 may also include grey areas 915 correspond to the volume of posts occurring (e.g., for example, as a burst of posts) within the temporal segments. Keywords associated with the posts 910A-910H may also be displayed in regions 920 adjacent to the curve 905. The process for generating the curve is discussed in greater detail below with respect to FIGS. 10-14.

To adequately and intuitively present conversational threads, example implementations of the present application may attempt to reveal both overall trends and post-level information in a single representation. To attempt to achieve these goals, example implementations of the present application may use a curving representation illustrated in FIG. 9 discussed above including the key phrases extracted from the posts to summarize the content of conversational threads (e.g., Regions 920).

FIG. 15 illustrates a flow chart of a process 1500 for generating a visual representation (e.g., FIG. 9) in accordance with an example implementation of the present application. Before visualization may be generated, a plurality of posts to be represented is required. In some example implementations, the plurality of posts may be provided in advance of the process 1500. In other example implementations, the plurality of posts may optionally be collected at 1505. The plurality of posts may be collected from a posting or messaging platform as may be apparent to a person of ordinary skill in the art. In some example implementations, the plurality of posts may also include time stamp data indicating dates and/or times of posting and may also include keyword or content information indicative of subject matter associated with the post or message. Once the plurality of posts is collected, the visual representation may be generated using the following steps.

Adaptive binning of posts. As a first step of generating a curve (e.g. curve 905 of FIG. 9), a plurality of posts are adaptively binned at 1510. In other words, based on the timestamps associated with each post, the plurality of posts may be sorted into short time intervals represented by bins (e.g., 5 min time intervals associated with Bins). FIG. 10 illustrates a graphical representation 1000 of the binning process. As illustrated, a plurality of messages 1005A-1005H may be divided into a plurality of bins 1010A-1010G. As illustrated, two messages or posts 1005A and 1005B are placed in the first bin 1010A. Further, one message or post is placed into each of bins 1010B and 1010C (post 1005C is placed in bin 1010B and post 1005D is placed in bin 1010C). Additionally, one message or post is also placed into each of bins 1010D and 1010E (post 1005E is placed in bin 1010D and post 1005F is placed in bin 1010E). Finally, one message or post is placed into each of bins 1010F and 1010G (post 1005G is placed in bin 1010F and post 1005H is placed in bin 1010G). In some example implementations, the time interval of each bin may be determined by dynamically based on the available number of pixels to show the curve on the screen. If the number of pixels is smaller, the time interval will be larger.

Generating the Curve.

After the messages or posts have been divided into bins, a curve representing the posts may be generated at 1515. FIG. 11 illustrates a graphical representation 1100 of the curve generating process. As illustrated, based on the numbers of posts in the above bins 1010A-1010G, locations of dots representing points on a display screen that the curve must pass through are calculated. For example, a first dot 1105A may be centrally located within the bar representing the first bin 1010A. The widths of each of the bars representing the bins 1010A-1010G may be proportional to the numbers of posts within each bin 1010A-1010G. Once the first dot 1105A has been placed, additional dots 1105B-1105H may be placed alternating between left and right edges of the respective bins 1010A-1010G, as shown in FIG. 11. Finally, another dot 1105I corresponding to the last message in a sequence may also be centrally located on the last bin 1010G. Using these dots 1105A-1105I, a zig-zag B-spline curve 1110 can be generated using any computer graphics methodologies, which might be apparent to a person of ordinary skill in the art.

Generating the Volume Area.

In parallel with, prior to or subsequent to, generating the curve illustrated in FIG. 11, the volume area associated with the curve may also be generated at 1520. The volume of the curve may be generated in a process similar to the process used to generate the curve. FIG. 12 illustrates a graphical representation 1200 of the curve volume generating process. As illustrated, based on the numbers of posts in the above bins 1010A-1010G, locations of dots representing points on a display screen that edges of the curve volume must pass through are calculated. For example, a pair of first dots 1205A, 1210A may be centrally located within the bar representing the first bin 1010A.

Again, the widths of each of the bars representing the bins 1010A-1010G may be proportional to the numbers of posts within each bin 1010A-1010G. Once the first pair of dots 1205A, 1210A has been placed, additional dots 1205B-1205H, 1210B-1210H may be placed along the left and right edges of the respective bins 1010A-1010G, as shown in FIG. 12. Finally, another pair of dots 12051, 12101 corresponding to the last message in a sequence may also be centrally located on the last bin 1010G. Using the dots 1205A-12051, a zig-zag B-spline curve 1215 can be generated on the left edge of the bins 1010A-1010G using any computer graphics methodologies, which might be apparent to a person of ordinary skill in the art. Similarly, using the dots 1210A-12101, a second zig-zag B-spline curve 1220 can be generated on the right edge of the bins 1010A-1010G also using any computer graphics methodologies, which might be apparent to a person of ordinary skill in the art.

As shown in FIG. 12, green points 1205A-12051 indicate the passing-through points of left edge of the volume of the curve 1110, and red points 1210A-12101 indicate the passing-through points of the edge of the volume of the curve 1110.

Ranking and Selection of Posts.

In some example implementations, there might not be enough space on a display screen to illustrate every post on the curve as the foreground. Thus, posts within each bin may be ranked and then selected according to the rank at 1525. For example, in some example implementations, the ranking may be based on the average weight of the extracted keywords in each post. The total number of posts that may be selected may be determined by the curve segment length available on the screen in terms of pixels.

Computing the Circle Positions.

After the representative posts to be displayed on the curve are selected, each selected post may be positioned on the curve at 1530. FIG. 13 illustrates a graphical representation 1300 of the circle positioning computation process. As illustrated, each post is presented by a dot 1305 placed on the curve 1110 by assigning a y-position based on a timestamp associated with the post. The x-position of the dot 1305 associated with the post may be determined by the intersection of the curve 1110 and the horizontal line 1310 passing through the y-position associated with the time stamp of the post. This may ensure that each of the post circles is drawn on the curve 1110.

Computing the Keyword Positions.

After the circle positions are calculated for each post to be shown, the keyword positions are computed at 1535. The keyword positions may be calculated using a force-directed layout method. FIG. 14 illustrates a graphical representation 1400 of a post curve 1405 with the posts 1410A-1410H. As illustrated, a plurality of keywords 1415A-1415J are positioned relative to the posts 1410A-1410H. The initial Y-position of each keyword 1415A-1415J may correspond to the Y-position of the associated posts 1410A-1410H where they are extracted. In order avoid Y-axis overlap, a repulsive factor or force may be applied between keywords 1415A-1415J to spread the keywords along the Y-axis. The X-axis position of each keyword 1415A-1415J may always be fixed to ensure that the keywords are vertically aligned.

Rendering.

Once the keyword positions have been calculated, a final step may be to render all the corresponding visual elements on the screen to produce the graphical representation 1400 illustrated in FIG. 14 at 1540. In some example implementations, the above computation process may be adaptive to the time-scale and available the display screen space. In some example implementations, the visual representation may attempt to provide as much important information as possible without producing too much visual clutter or visual complexity based on the available display screen space.

Once the visualization has been rendered, the process 1500 may end. The process 1500 may generate a single curve or visual representation of a single conversational thread. In some example implementations, multiple threads may be placed according to starting and ending times specified on a display window without overlap. In the embodiments discussed above, the specified display windows may be days or weeks (e.g., “Wed 24” in FIG. 5).

In some example implementations, curves may also be produced without post circles and keywords may be produced (e.g., FIG. 4, and curves 405A, 405F of FIG. 5) in a similar way. However, instead of rendering posts as circles, the corresponding curve segments may be colored based the majority of users in that segment.

In some example implementations, other aspects of the curve may be modified to illustrate the posts or messages instead of providing the dots associated with different posts. For example, the thickness of the line may be varied based on the number of posts represented by the curve. Alternatively, broken lines may be used to illustrate regions of no posts and solid lines may be used to illustrate regions of many posts. Additionally, in some example implementations, multiple curves may be nested over overlapped to illustrated comparative changes in topics or posting patterns in real-time. For example, curves 405C and 405E of FIG. 5 may be overlaid to show posting patterns by members of the same team on different topics in real-time.
